Nobody is a whole chain. Each one is a link. But take away one link and the chain is broken. We need each other. You need someone and someone needs you. Isolated islands, we’re not.
From Colossians 1:9-10: “For this reason, since the day we heard it, we have not ceased praying for you and asking that you may be filled with the knowledge of God’s will in all spiritual wisdom and understanding, so that you may lead lives worthy of the Lord, fully pleasing to Him, as you bear fruit in every good work and as you grow in the knowledge of God.”
